8-Ch/Dual 4-Ch High-Performance CMOS Analog Multiplexers
DESCRIPTION
The DG408 is an 8 channel single-ended analog multiplexer
designed to connect one of eight inputs to a common output
as determined by a 3-bit binary address (A0, A1, A2). The
DG409 is a dual 4 channel differential analog multiplexer
designed to connect one of four differential inputs to a
common dual output as determined by its 2-bit binary
address (A0, A1). Break-before-make switching action
protects against momentary crosstalk between adjacent
channels.
An on channel conducts current equally well in both
directions. In the off state each channel blocks voltages up
to the power supply rails. An enable (EN) function allows the
user to reset the multiplexer/demultiplexer to all switches off
for stacking several devices. All control inputs, address (Ax)
and enable (EN) are TTL compatible over the full specified
operating temperature range.
Applications for the DG408, DG409 include high speed data
acquisition, audio signal switching and routing, ATE
systems, and avionics. High performance and low power
dissipation make them ideal for battery operated and
remote instrumentation applications.
Designed in the 44 V silicon-gate CMOS process, the
absolute maximum voltage rating is extended to 44 V.
Additionally, single supply operation is also allowed. An
epitaxial layer prevents latchup.

TA201.

Notes
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this datasheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
g. RDS(on) = RDS(on) max. - RDS(on) min.
h. Worst case isolation occurs on channel 4 due to proximity to the drain pin.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
